javascript port communication

[hendy]

hi all....
i got a question..
can javascript open a port connection?
anybody knows?

thx anyway...

No :p

But bear in mind that JavaScript is parsed and "run" by the person's browser and because of that, each browser has its own standards and almost all return differently for obscure functions. Very few comply to the WC3 standard.

What I'm getting at is that it's up to the browser whether they have socket communication (it's not part of the standard, nor is it expected as far as I know, so don't get your hopes up).

Hope that helps :)

oh...
i think this page is for testing whether my client has that spesific port opened or not on their PC in order to use my application, before they encounter any other connection problem,
i think it's best to make sure this common problem solved first..
thx anyway

What JavaScript application needs to use ports in order to function?

You could use PHP to check if they weren't behind a firewall (like a router), but it's pretty pointless.

Just allow other port configuration options I guess.
